Abstract
A system for forming a plurality of polymer waveguides includes at least one collimated light source adapted to produce a plurality of collimated light beams; a channel having an exposure area for the collimated light beams to pass through and for holding a photo-monomer adapted to polymerize when exposed to the collimated light beams, the photo-monomer moving with respect to the plurality of collimated light beams; and a mask disposed between the at least one collimated light source and the photo-monomer. A method for forming a plurality of polymer waveguides includes moving a mask across an exposure area of a channel containing a photo-monomer; exposing the photo-monomer to collimated light through the exposure area of the channel; growing the plurality of polymer waveguides from the exposure area into the photo-monomer to form an interconnected ordered three-dimensional polymer micro-truss structure; and removing the ordered 3D polymer micro-truss structure from the channel.
